Abstract

There's some key problems of transmission of multi-service mixed signals in fibers for C-RAN, so the influence of dispersion and crosstalk on transmission of mixed signals is researched. Besides, the evolution of multi - service signals is theoretically analyzed. A scheme for transmitting mixed signals is proposed, by which the optical carrier will filtered. The carrier loading mixed RF signals are modulated by direct modulation. Then mixed signals will be transmitted. Mixture transmission of LTE signals and random radio signals is simulated, obtained the maximum transmission distance of signals at which signals can keep high-quality, with the help of the analysis of performance of the transmission system. This transmission distance can meet the demand of access networks, which means that the proposed scheme is available.
